Finnfoam – durable and waterproof

Finnfoam is an XPS thermal insulation product made from extruded polystyrene, which retains its insulating capacity in even the most demanding conditions. The panels special feature is its completely closed and consistent cell structure, which ensures a high insulating capacity and impermeability. In addition to thermal insulation, Finnfoam also facilitates various other construction stages, thus enabling high-quality and energy efficient results. Structures produced using Finnfoam do not require separate vapor barriers or wind-proofing panels, which means that a single installation takes care of several work elements. Finnfoam is also mold-proof, as verified by VTT using the most stringent mold testing available.

Versatile insulation – from pipe trenches to attic roofs

The entire range is suitable for use as frost insulation and for insulating floors, ceilings, and walls, as well as various in supplementary thermal insulation applications. As frost and floor insulation, Finnfoam is highly resistant to moisture, freezing, and load. After all, reliability is the most important property of frost insulation, and its insulating properties cannot be allowed to deteriorate over time. The freeze-thaw-resistance of frost insulation products should always be specified. As a prime example of Finnfoam's reliability, it claimed first place in a frost insulation comparison performed by the TM Rakennusmaailma magazine in the fall of 2011.

For almost 40 years, Finnfoam has been relied on for various demanding applications ranging from train tracks to public buildings, shopping centers, and industrial facilities. We also provide excellent solutions for the construction of business premises, housing, low rise buildings, and infrastructure.
